Triquetra is a word derived from the Latin tri- ("three") and quetrus ("cornered"). Its original meaning was simply "triangle" and it has been used to refer to various three-cornered shapes. Nowadays, it has come to refer exclusively to a certain more complicated shape formed of three vesicae piscis, sometimes with an added circle in or around it. It bears a resemblance to the Odin knot, or Valknut.

The triquetra has represented many things for many religions and cultures. It has been used as a powerful amulet since ancient times. To the Christians it symbolizes the Father, the Son & the Holy Spirit. The triquetra shape incorporates the Ichthys (fish) used as a secret symbol by early Christians. To the Wiccans it symbolizes the triple goddess, or 3 stages of a womans life; Maiden, Mother & Crone. It symbolizes many things across many religions and cultures. The constant cycle of Life, Death and Rebirth; the triplicities of Mind, Body, and Soul; the three domains of Earth, Sea, and Sky; the Taoist concepts yin, Tao and yang; the tantric energy channels ida, sushumna and pingala; the Hindu trinity Shiva, Brahma and Vishnu; the alchemical concepts Sulfur, Mercury and Salt; the phases of the moon waning, full and waxing; and the Hebrew letters Mem, Aleph and Shin.

In the post-modern world it symbolizes the Power of Three lovely witches from the immensely popular Charmed on the WB. The unbroken circle symbolizes the essential unity of whatever triad is being signified by the three outer points and the central, curved triangle.

Triquetra, triqueta, trinity knot, triangle knot, celtic knot, all of these are names you will hear to describe this type of design. Many triquetras have an eternity circle to emphasize the unity aspect, but not all.
